Abstract
We report measurements of radiative B decays with Kηγ final states, using a data sample of 253 fb−1 recorded at the Υ (4S)
resonance with the Belle detector at the KEKB e+e− storage ring.We observe B+→K+ηγ for the first time with a branching
fraction of (8.4 ± 1.5(stat)+1.2
−0.9(syst)) × 10−6 for MKη < 2.4 GeV/c2, and find evidence of B0→K0ηγ . We also search for
B →K∗3 (1780)γ .
